VEHICLE-WHEEL TIRE.

Specification of Letters Patent.

Application filed September 18, 1909. Serial No. 518,368.

' To all whom it may concern:

Be it known that I, ANTONY T. SOARA- MUzzi, a citizen of the United States, residing in Paterson, Passaic county, New J ersey, have invented a certain new, and useful Im rovement in Vehicle-Wheel Tires; and I 0 hereby declare the following to be a full, clear, and exact description of the 1nvention, such asv will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

This invention relates to inflated vehiclewheel tires and particularly to that class of such tires which employ inner tubes, and it has for its object to provide means for reventing puncturing of'the tire while alowing the tire to retain the desired elasticity and resiliency. A further objectis to make a tire of the kind indicated puncture-proof without its being specially constructed to that end and so that a tire already in use may be readily fitted with the protectin means. To this end I- provide a series of articulated puncture-resisting leaves or plates, each crosssectionally' shaped to conformsubstantially to the curvature of the cross-section of the tread of the tire, inclosing them in a tough, durable casing, preferably formed of sheets of leather lying against the upper and lower sides of the leaves or plates and so formed as to confine the leaves or plates against lateral movement in the casing; this casing, besides resisting puncturing influences to a large extent on its own account, serves,

partly by adhering to the inside of the tire proper under the pressure of the inner tube and partly by abutting against a stop formed, say, by the rim of the wheel, to revent the protecting means from creeping aterally, and at the same time it assumes the wear of the articulating plates or leaves,

, particularly at their ends, and allows the series of platessome slight sli in the direction' of the circumference of tlEe tire, so that the wearing points of the lates or leaves on the casing and consequeniily on the treadportion of the tire proper are constantly.

0 ng, ,fafizive fully illustrated my invention in the accompanying drawing, wherein,

Fi re 1 1s a. cross-sectional view of a tire provided with the improved protecting tudinal ed es;

so that, w ile lying flat against the inner means, on line w-w, Fig. 4; Fig. 2 shows, in sideelevation, several of the leaves or plates ext-ended; Flg. 3 1s a sectional view on line y of Fig. 3 Fig. 4 is a longitudinal sectional view of the tread-portion of the tire proper and shows the protecting lneans' in side elevation, partly broken away, and Fig. 5 is a longitudinal sectional view showing a modified construction of the leaves or plates.

at designates the rim of the wheel having the opposed grooves I); ois the tire proper having the lateral ribs or flanges d adapted to lock in the grooves b; and e is the inner tube.

f desi nates one of a series of plates, preferably' o med of metal; the blank from which sai plate is produced is rectangular in shape and when the plate'iscompleted it hasthe cross-sectional curvature shown in 'Fig. 3 and at each of its four corners a hole g, h, the two holes it being slightly farther. from the lateral edges of the plate than the other two, 9. Said plates are secured-together in a circular series by means of rivets a, which form pivots allowing the plates to articulate on each other; the holes h in one plate being farther removed from its lateral edges than the holes 9- are from the lateral edges of the next adjoining plate, each plate is eccentric with respect to the other, allowing the pivotal movement. At one or more points in the circular series of plates, where necessary,-'the holes g (or h) may. be elongated, as shown at 1a,.Fig. 2, to permit a slight expansion and contraction of the serlGS. 1

The series of plates is inclosed in a to h durable. casing or envelo Z, preferab y composed of leather. Said casing comprises strips of leather m and n stitched to-' gether along the lines o and also, referably, along the lines p, parallel with t eir longit e casing is sulficiently wide surface of the tire roper when the inner tube is inflated, t e longitudinal edges thereof will abut against each other and also a ainst some part of the structure envelo i'n'g-it as the mm a.

I "amt be first introduced, belng laced in the dissition shown in Fi' 1 ;-t on the inner tube. is inserted between te longitudinal I ling the parts of a, vehicle wheel thus constructed, the protecting means may I eedlges of E the casing, the tire, proper interlock with 5 the ni r fs f th it andthe inner tube inflated. The plates, While protecting the innertube from being unetured,perm1 t the tire to retain it re's1iency' and elasticity both because they are articulatedand heceuse expansion and contraction are allowed .in the series of plates atthe' points Move; I ilint of theprbtecfiri 'means in the lateral direction .is prevente hry the edges of the casing abutting against each other and and movement thereof in e longitudina direction is prevented by the adhesion which-exists between the casand the inner surfaceof the tire proper under the .pirl'essure ofthe inner tube; foldogt the casin is. therefore eother hand, t e plates f being. or "-buc plates .longitudinallyiin the easing is permitted, (the same having the efiect of-chang -i-ihg-the' points of wear of saidplates-on the =casin iconstantly.
